Power Management IC
The DA9030 power management IC (PMIC) supports both a communications processor and the Intel PXA27x family of applications processors in next-generation mobile handset designs. Updated to support standalone Intel PXA27x processor-based applications, it minimizes power consumption.
Enhanced Optical Isolator
The OPI1268 high-voltage optical isolator consists of an infrared LED and photologic sensor. Capable of dc and ac voltage isolation between the input and output circuitry while providing TTL signal integrity, the maximum isolation voltage is 16 kV with propagation delays less than 200 ns.
TT electronics/Optek Technology
These 5-V single-output eighth-brick dc-dc converters provide industry-leading conversion efficiencies of 92%. These latest additions to the Typhoon family of high-performance board-mounted power conversion products have current ratings of 10 A and 15 A, with 20 A in the near future.
Artesyn Technologies Inc.
MAX5071A/MAX5071B single-ended current-mode PWM controllers are for isolated telecom dc-dc or universal offline-input ac-dc power supplies. They are pin-compatible with the industry-standard multi-sourced UC2842/UCC2842 and UC2844/UCC2844 (the feedback FB pin is replaced with a bidirectional SYNC input pin).
Maxim Integrated Products
Both the ISL6402 and ISL6402A contain two synchronous-buck PWM controllers and a linear regulator in a near-chip-scale thermally enhanced 28-pad quad flat no-lead (QFN) package and a 28-lead TSSOP package. The ISL6402 is efficiency optimized for several applications, while the ISL6402A is for xDSL customer premises equipment (CPE) compatibility.
Intersil, Milpitas, Calif.
The HBQ12R135 functions as a bus converter in distributed architecture applications or provides isolated 12-V output where needed. It's cost effective, yet meets the requirements of 48-V telecom, networking and datacom applications. Features include industry-standard quarter-brick size and high efficiency with 162 W of power.
Shindengen America Inc.
The LTC3443 buck-boost dc-dc converter delivers up to 1.2 A of output current at efficiencies as high as 95%. Designed to optimize battery run time for single-cell Li-Ion, multi-cell alkaline or NiMH battery-powered applications, it operates from an input voltage range of 2.4 V to 5.5 V and can provide up to 1.2 A of output current at a fixed output voltage between 2.4 V to 5.25 V.
